mysql - 在hadoop上使用sqoop import命令时出现错误

Question

您好，我正在使用以下sqoop命令，我认为应该可以使用

[cloudera@quickstart ~]$ sqoop import --connect jdbc:mysql://quickstart.cloudera:3306/retail_db --username root --password cloudera --query "select * from customers where customer_street like '%Plaza%' AND $CONDITIONS" --target-dir /user/cloudera/problem1/customers/textdata --fields-terminated-by '*' --lines-terminated-by '|' --as-textfile --columns "customer_id,customer_fname,customer_lname,customer_street" --split-by "customer_id"

但是我得到以下与$ condition相关的错误，我认为该错误已正确实现..请帮助..谢谢

您好以下应该可以使用

 sqoop import --connect jdbc:mysql://quickstart.cloudera:3306/retail_db --username root --password cloudera --query "select * from customers where \$CONDITIONS AND customer_street like '%Plaza%'" --target-dir /user/cloudera/problem1/customers/textdata --fields-terminated-by '*' --lines-terminated-by '|' --as-textfile --columns "customer_id,customer_fname,customer_lname,customer_street" --split-by "customer_id"
